Conservation Status Assessment Of The Egg-Mimic Darter (Percidae: Etheostoma Pseudovulatum) Using A Multi-Faceted Approach, Zachary L. Wolf, John W. Johansen, Rebecca E. Blanton Mar 2022

Conservation Status Assessment Of The Egg-Mimic Darter (Percidae: Etheostoma Pseudovulatum) Using A Multi-Faceted Approach, Zachary L. Wolf, John W. Johansen, Rebecca E. Blanton

Southeastern Fishes Council Proceedings

The imperiled Egg-mimic Darter (Etheostoma pseudovulatum) is a headwater-adapted fish restricted to an area less than 1000 km2 in Tennessee. It is found in only six tributaries of the Duck River and the large, mainstem of this system may act as a barrier to dispersal, restricting population connectivity. The only status assessment of this species was over two decades ago; genetic diversity and the degree of population connectivity have never been evaluated. We conducted a conservation status assessment using a multi-faceted approach to better inform conservation management plans, including examining its current distribution, assessing habitat quality, estimating …


Investigating The Effects Of Climate Change On The Phenology Of Achillea Millefolium, Aquilegia Coerulea, And Penstemon Cyanocaulis, Hannah O’Toole, Kailey Hicks, Lisa Long, Jackson Garske, Anna Sher Jan 2022

As the effects of climate change are starting to unearth themselves, the impacts can be observed by tracking the patterns of cyclical natural phenomena also known as phenology, and monitoring how they have changed over time. These cycles are at the crux of making ecosystems viable for their local biodiversity, and understanding the ongoing change allows for further understanding of the ecosystem’s change over time. In this study, we look at the ordinal flowering dates of the Achillea millefolium, Aquilegia coerulea, and Penstemon cyanocaulis over the past century. Our data give insight into how warmer temperatures occurring earlier in …


Landscape Characteristics Predict Locations For Potential Human–Wildlife Interactions With Timber Rattlesnakes In Minnesota, Usa, Ben M. Borash, Benjamin P. Pauli Jan 2022

Landscape Characteristics Predict Locations For Potential Human–Wildlife Interactions With Timber Rattlesnakes In Minnesota, Usa, Ben M. Borash, Benjamin P. Pauli

Human–Wildlife Interactions

While management measures cannot eliminate human–wildlife conflicts, they have the potential to minimize the damage done to both parties, especially if areas where the nature of the potential interaction can be predicted before an encounter occurs. The timber rattlesnake (Crotalus horridus) represents a wildlife species associated with public misconceptions that may foster unwarranted fears and retribution. This species is native to the eastern and southern regions of the United States, including a small population remnant in the southeastern region of Minnesota. To gain a better understanding of the environmental predictors relevant to human–snake encounters in Minnesota (that require …
